Rescued or Not
From Halopedia, the Halo wiki
Rescued Or Not is the sixteenth track from the Halo Wars: Original Soundtrack, released on February 17th, 2009.
It is played through the Halo Wars campaign level Beachhead's opening cutscene, "Judgement Day", where the Arbiter uses Ellen Anders to activate the Forerunner dreadnoughts.
The track's name is derived Sergeant Forge's last words of the cutscene; "Lady, I haven't got all day. You wanna be rescued or not?".
